STOPPER FOR RENDERING BOTTLES NON-REFILLABLE.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed July 11, 1916. Serial No. 108,703.

To all whom it may concern:

Be it known that 1, Luis ARNAVAT OLrvii, a citizen of theUnited States of America, residing at 2 Obispo, Barcelona, in the Kingdom of Spain, have invented a certain new and useful Improved Stopper for Rendering Bottles Non-Refillable, of which the following is a specification.

The present invention relates to a stop per for rendering non-refillable, bottles to which it is fitted. The object of the invention is to provide a stopper of simple construction which is efiective for its purpose.

The improved stopper will now be described with reference to the accompanying drawing, in which" Figure 1 is an external elevation.

Fig. 2 is a longitudinal section of a stop per fitted to a bottle neck, inverted.

Fig. 3 is an analogous section but showing the bottle with its longitudinal axis horizontal.

Fig. 4 is a section on the line A-B of Fig. 2.

Figs. 5 and 6 represent details in plan.

The stopper consists of a hollow cylindrical casing 1 one end of which is provided with a valve supporting plate 2 forming a valve seat and fixed by means of a cement 21 applied beneath a flange 3 which serves by making a tight joint to prevent the adhesive material or cement from reaching the interior of the chamber in which the closing valve acts, as otherwise the regular operation of the valve would be impeded. The valve supporting plate 2 might also be connected with the receptacle 1 by means of a screw connection. v

The obturating members are constituted by: the valve 4, the cylindrical float 5 and the pressure ball 6.

When the bottle 7 to which the stopper is fitted is upright, the valve 4 is applied to its seat on the plate 2, closing being then in sured by the pressure of the ball 6 and of the float 5; when the bottle is inverted, the ball 6 rests upon its appropriate cup 8, so that, if the bottle should be immersed in a liquid, the float 5 will apply the valve 4 against its seat on the plate 2, thereby preventing the liquid from entering the bottle.

In the horizontal position (Fig. 3) the ball 6 bears against a stop 9 provided with this object on the bottom of the casing 1, in such a manner that the ball 6, the float 5 and the valve 4 are firmly held between the said stop 9 and the plate 2, thus preventing communication between the bottle and the exterlor, even if movement should be imparted to the bottle with the object of there bv causing a liquid to enter it.

An important 'feature of the improved stopper resides in the provision of a reduced length in the chamber of the casing 1, so that this chamber presents a shoulder 10 approximately correspondin with the middle part of the float 5; the object of this arrangement being that, when the bottle is inclined, the float may rock, thereby insuring its movement, any adherence between the chamber of the casing 1 and the float 5 being thus overcome. Such adherence would introduce a disturbing element into the functioning of the device.

On its inner face the plate 2 presents ribs 11, which are seen most clearly in Fig. 5, and which produce alternating restrictions of the inlet; this arrangement in conjunction with the orifices 12 intermediate of the ribs, serves the purpose that when the bottle is inclined, for pouring out its liquid contents, the latter is split up into jets and the outer air is able to enter, so that the liquid issues uniformly and insures the functioning of the stoppering elements 4, 5 and 6 in such a manner that they do not impede the uniform flow of the liquid. With'the same object, the non-return valve 4 comprises channels such as '15, or, instead of being provided on the valve, these channels might be formed on the wall of the chamber of the receptacle 1 and produce the same efiect; or they might be formed upon both parts.

When the bottle is intended to contain oily or mucilaginous liquids, the seat member described is replaced by the seat member represented in Fig. 6 which in place ofthe outlets 12 presents a single, larger aperture 14 in the form of a star whose points act in combination with the corresponding system of ribs 13, for the purpose already explained.

Discharge apertures 16 are arranged in the bottom of the casing 1 in such a manner that their walls are very thin so that the edges will break readily if a wire should be introduced from the exterior with a view to forcing the stopperingdevice so that the attempt is rendered obvious. The detail view Fig. 4 clearly shows the arrangement of the discharge orifices 16.

On the outer face of the portion 17 which is of reduced diameter the receptacle 1 presents longitudinal channels to permit of permanently fixing to this portion a cylinder or lining 18 of cork or other appropriate material, intended to cause the stopper to fit the bottle neck snugly.

The various parts of which the stopper that has been described is com osed may be constructed of any suitable materials and they may be covered with a protecting coating of varnish and, if thought desirable, a part (such for example as the outer thread 19) may be left unvarnished, So that it will be attacked if an acid should be used with the object of removing the stopper from the bottle with fraudulent intent.

The improved stoppering device is applicable to all kinds of bottles, pots, jars and receptacles in general.

I claim:

1. A stopper for rendering bottles nonrefillable, comprising a hollow cylindrical casing adapted to fit into the neck of the bottle and to contain the obturating means, viz: the valve, the float and the pressure ball and having its upper end closed and provided with laterally disposed outlet holes inaccessible from the mouth of the neck, a valve supporting plate at the lower open end of the said hollow cylindrical casing, said valve supporting plate having a number of holes therein, a continuous fiat upper surface and an outwardly protruding flange secured to the lower end of the said casing, the said casing being provided near its lower extremity with an inwardly protruding flange above the extreme edge of the easing making tight contact with the peripheral surface of the said valve supporting plate, a valve having flat top and bottom faces and adapted to lie upon the flat upper surface of the said supporting plate, a float separate from the said valve and adapted to lie upon the valve, and a pressure ball adapted to lie upon the float, substantially as described.

2. A stopper for rendering bottles nonrefillable, comprising a hollow cylindrical casing adapted to fit into the neck of the bottle and to contain the obturating means, viz: the valve, the float and the pressure ball, and having its upper end closed and provided with laterally disposed outlet holes inaccessible from the mouth of the neck, the said casing being reduced to form, an internal annular shoulder, a valve supporting hollow plate carried at the lower open end of the said casing, said valve supporting plate being provided with holes, a valve adapted to lie upon the said valve supporting plate and to close the said holes, a cylindrical buoyant body mounted lengthwise in the cylindrical casing and above the supporting plate in a position with the middle part of its length approximately corresponding to the internal annular shoulder formed in the casing, and a pressure member adapted to lie upon the buoyant body, substantially as described.
